Alright, let's solve this math problem step by step. First, we have the number 85. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 12. So, we're going to take the number 85 and add it to itself 12 times.
Step 1: 0 + 85 = 85
Step 2: 85 + 85 = 170
Step 3: 170 + 85 = 255
Step 4: 255 + 85 = 340
Step 5: 340 + 85 = 425
Step 6: 425 + 85 = 510
Step 7: 510 + 85 = 595
Step 8: 595 + 85 = 680
Step 9: 680 + 85 = 765
Step 10: 765 + 85 = 850
Step 11: 850 + 85 = 935
Step 12: 935 + 85 = 1020

So, 85*12 = 1020
